SeeTool - Solutions for KNX Office building segment Application 8.2.1.0.0.4 Movement dependent automatic light control with light regulation and manual control, temperature control (electrical heating with 16A Solid State Relay and cooling with KNX EMO valve drive) and blind/ shutter control, single room
Lighting, temperature and blind/shutter control functions Lighting and temperature control functions: The lights are automatically switched ON or OFF dependant on people s movement and existing brightness. When the lights are on, the light controller in the presence detector maintains the decided lux set point by dimming the lamp actuator dependant on the available daylight. In addition three predefined light levels and a permanent OFF can be activated manually by push-button. Temperature controller tries to keep room temperature at it s setpoint by controlling Solid State Relays for heating and a KNX EMO valve drive for cooling. The movement detection will automatically set the temperature control either into comfort or standby mode. A connected window contact will set the temperature control into frost/heat protection mode when the window is open. Blind/Shutter control functions: A blind or roller shutter motor with end position can be connected to each channel of the blind actuator. The position of the blind s or shutter s height can be adjusted manually by pushbuttons. At slat-blinds an adjustment of the slat s angle is possible as well. Lighting Application areas The application is defined to be used in office rooms and/or conference rooms where the level of light will be kept constant taking into account the amount of natural light. The solution offers sophisticated control of the lighting, heating and cooling with an automatic movement detector and additional manual control plus an open window sensing function to set temperature at comfort and standby mode. Temperature Energy savings Combining the presence and daylight function with temperature control to the room application, we are able to utilize the daylight and temperature factors to optimize and save energy during the active period of use throughout the year. Presence dependant lighting control plus daylight harvesting can achieve a 60% electricity saving compared to installations without automatic function. At temperature side presence dependant control can lead to savings of up to 20% yearly in compare to rooms without automatic control functions. Future proof The application is prepared and defined for integration into a Building Management System if required, through the open technology communication network. Flexibility For optimized costs the device s functional interaction is predefined. Functionality can be modified or changed at any time in the lifecycle and allows a maximum of flexibility and adaptation when walls are removed and rooms combined. Reliability Design, planning and installation documents are pre-defined which makes the entire building process faster and more reliable. User documents and descriptions are prepared to assist in user training. The application works as an individual, stand alone room control unit or combined with the entire network.

Functions Lighting control: The lights are automatically switched ON when a person enters the room and the brightness value is below the selected brightness threshold. If no movement is detected within a delay time of 25 minutes, the light will be dimmed down to minimum. If no movement is detected for another 5 minutes the light will be switched off. When the lights are on, the light controller in the presence detector maintains the decided lux set point by sending dimming telegrams to the lamp actuator. functions If the daylight will increase, the regulation dims down the artificial light. If it decreases, the regulation will dim up the artificial light. The lux set point after download and power failure is adjustable by ETS software. The default lux setpoint at the reference surface (e.g. desk) is 500 lux ±20% hysteresis. The user can also select the lux setpoint by the push-button unit. Button 1 will give high brightness (500 lux), button 2 will give medium brightness (300 lux) and button 3 low brightness (100 lux). With button 4 permanent- OFF can be activated. The light will then be off until one of the other buttons is pressed. When permanent OFF is activated the status LED next to the button is blinking. Temperature control: Temperature controller tries to keep room temperature at it s setpoint by controlling SSR s (Solid State Relay) pulse width from 0 to 100%. SSR is totally silent so it could be installed more freely. If comparing to mechanical relay its lifetime is much longer because there is not any moving parts inside. SSR switches ON and OFF in zero-crossing voltage so it don t generate any electrical noise to the power line. Cooling is controlled by a KNX EMO valve drive. Movement detection will automatically set the temperature control into comfort-mode. To save energy this will not happen until a person has been in the room for more than 3 minutes. In this way the temperature control is not affected if someone is present in the room just for a short period of time. If no movement is detected within a delay time of 25 minutes the temperature control is set into standby-mode. If a window contact (breaking contact) is connected to the EMO valve drive the temperature control will be set into frost/heat protection mode when the window is open. Comfort-mode: default room temperature setpoint heating 21 C cooling 24 C Standby-mode: default room temperature setpoint heating 19 C cooling 26 C Frost/Heat protection: heating 7 C cooling 35 C The setpoint can be adjusted by the user +/- 3 C from given setpoint. This is done by pushing invisible buttons on both sides of the display frame. Blind/shutter control: A blind or roller shutter motor with end position can be connected to each channel of the blind actuator. The position of the blind s or shutter s height can be adjusted manually by push-buttons. With a long pressure on button 5 the blind or roller shutter moves upwards. With a long pressure on button 6 the blind or roller shutter moves downwards. With a short pressure the movement of the blind or shutter stops. In the case of a blind or hanging with slats the angle of the slats can also be moved stepwise with several short pressures. With button 6 the slats turn to the position 100% closed or to the mechanically determined working position. With button 5 the slats move to the opposite direction. The possible angles of the slats depend from the mechanical construction of the blind with slats. Scene control: A scene for a beamer presentation can be recalled with button 7. Thereby the blinds or shutters will be lowered to 80% closed and the light will be set to a low lux-level (50 lux). By use of button 8 the blinds or shutters will be moved completely upwards again and the standard lighting level (500 lux) will be activated.

Note Number of controlled electronic interfaces highly depends on used ones, check with manufacturer recommendations. An electronic interface takes high inrush current. It is recommended that Type C MCB s (Miniature Circuit Breaker s) are used. Using Type B leads to decreased number of units. If window contact is not used, green and yellow wire has to be tied together (shortcircuit). Configuration settings The ETS tool is used to set the parameters for the devices in the application and to define the functional relationship between the devices by group addresses. The following parameters and group address relations must be set and assigned. The parameters should be set first and in the described order. The parameters which can be changed to fine tune the application are described further on.

Actual value correction The measured brightness value (actual value) can be corrected. A distinction is drawn here between the installation location of the presence detector and the reference area (a desk surface, for example). The brightness value of the reference area is determined with the aid of actual value correction and taking the brightness value measured by the presence detector at the installation location and an internal adjustment curve into account. In the case of light regulation it is not the brightness value at the installation location which is important but the brightness value at the reference area (desk). For actual value correction you will need a luxmeter (example: Roline TES-1335 or equivalent). Four measurements are required for actual value correction: With the artificial lighting switched OFF, brightness is measured at the presence detector installation location. With the artificial lighting switched OFF, brightness is measured at the reference area (desk, for example). With the artificial lighting switched ON (maximum brightness), brightness is measured at the presence detector installation location. With the artificial lighting switched ON (maximum brightness), brightness is measured at the reference area (desk, for example). settings The measurements can be done in daylight but not in clear sunshine, best condition is cloudy weather. To switch ON to maximum brightness a value telegram 100% can be sent from ETS to the value object of the control unit, for example. Note: the presence detector should not be in operation at this time. The four lux values measured must be entered as parameters in ETS.

Fine tuning Some parameters can be changed to fine tune the solution to the building and specific requirements. Parameter which may need to be adjusted are listed below, our recommendation in brackets. KNX ARGUS presence detector with light control and IR receiver: The staircase timer (delay time) will be retriggered by every detected movement when the light is on. The light will be dimmed down to minimum if no movement has been detected within the specified time. If no movement is detected the light will stay on minimum level for a time period specified by the parameter dimming down time. After this time the light will be switched off. fine tuning General light control > Control response in automatic mode > Times General light control > Control response in automatic mode > Times General light control > Switching off in automatic mode General light control > Switching off in automatic mode Delay time = Time base x Time factor Dimming down time = Time base x Time factor Lux level setpoint in reference area Time base for staircase timer 1s/1 min/1h (1 min) Time factor for staircase timer 1-255 (25) Time base, dimming down time Time factor, dimming down time 1-255 (5) General light control >l Control response in auto. mode > Brightness General light control >l Control response in auto. mode > Brightness Nominal value reference surface 1 s/1 min/1 h (1 min) 10-2000 lux (500 lux) Hysteresis 10%-50% (20%) The actual brightness value (corrected measured value) can be sent cyclically to the bus via communication object 107. This can be used for test purpose together with ETS. If it is used for other purposes, the value should not be sent too often for bus load reasons. If there is no receiver to display the value in the project, the function should be disabled after the test phase.

Fine tuning The delay time for changing between standby-comfort is dependent on presence activity in a room. To save energy the switch-over from standby to comfort is done when movement is detected after a specified dead time. Then a staircase timer is started which will be retriggered by every detected movement. If no movement is detected the staircase timer will run out and standby mode is activated again.

In the configuration of each channel blind or roller shutter can be selected. Channel config. Channel 1 operation mode Blind / Roller shutter In the case of the blind configuration additional parameters for the fine tuning of the behavior of the slats are available. In the case of roller shutter these parameters are not necessary and can not be selected. 13
Defining blind type (only for blind with slats) The application differentiates between four types of blind. You can determine the blind type from the position of the slats during movement. Types 2 or 4 (slats are downwards titled) should be selected when the slats have a mechanically determined working position. The working position restricts the possible opening angle of the slats, as long as the blind has not reached its lower end position. fine tuning Blind type (1) without working position downwards closed / upwards horizontal Blind type (2) with working position downwards tilted / upwards horizontal Blind type (3) without working position downwards closed / upwards closed Blind type (4) with working position downwards tilted / upwards closed 1:Blind How does the existing blind move? (1) downwards closed / upwards horizontal (2) downwards tilted / upwards horizontal (3) downwards closed / upwards closed (4) downwards tilted / upwards closed Caution! Some blinds have special drive characteristics which are not congruent with one of the four types of blinds. In this case an exact positioning of the slats might be impossible. 14
Slat position after movement (only for blind with slats) 1:Blind Slat position after movement no reaction operating position (last slat position) The slat opening that you specify here is inter alia applied after a manual movement command ended by stop telegram. This is the standard way of control via long and short pressure with a push button. Please note: a mechanically determined working position restricts the possible opening angle of the slats, as long as the blind has not reached its lower end position (Blind types 2 and 4: slats are downwards tilted). fine tuning Recommendation: the slat running time should be set. When you select slat position after movement : last slat position or operating position it is necessary to know the slat running time. When you want to define the number of steps for opening or closing the slats you also need the running time. Height running times The blind actuator allows a precise positioning of the height with value objects. This positioning depends from the calculation of the running time of the used blinds and shutters. As various types of blinds and shutters are available it is not possible to recommend any default-value. You should measure the height running time from end to end position and set the following values: 1:Drive Time basis for height running time 10, (100) ms 1:Drive Factor for running time 10-64000 1 second = 1000 ms The drive needs this period of time to move out of one end position (blind/roller shutter is fully open or closed) into the opposite end position. When the set time expires the relay of channel 1 is automatically switched off (even if the drive with the values set here has not fully reached its end position). If you want to optimize the positioning behavior additional drive parameters can be set. 15
Slat running time (only for blind with slats) The slat running time is the period of time it takes the slat to complete a full movement from 0% to 100% or vice versa. The regulating range through witch the opening angle passes depends on the type of blind in use. Type (1): slats 100% = downwards closed and lower end position closed slats 0% = upwards horizontal Type (2): slats 100% = downwards tilted (= mech. working pos.) - lower end position = closed slats 0% = upwards horizontal fine tuning Type (3): slats 100% = downwards closed and lower end position closed slats 0% = upwards closed Type (4): slats 100% = downwards tilted (= mech. working pos.) - lower end position = closed slats 0% = upwards closed The opening angle after a movement of type (1) and (3) is directly influenced by the running time of the slats. The opening angle after a movement of type (1) and (3) is also influenced by the mechanically determined working position. The slats can only move up to the working position (e.g. 75%), as long as the lower end position of the height is not reached. When this end positions is reached, the slats can move up to the maximum value (100%). The measuring of the slat running time should be done at this lower end position. 1:Drive Time basis for running time of slat (10), 100 ms 1:Drive Factor for running time of slat 5-255 Slat step interval (only for blind with slats) Depending on the slat running time, the number of steps for opening or closing the slats can be defined. The time for one short movement of the slats is called step interval. E.g. slat running time = 1 second and step interval = 0.1 seconds > slats can be completely opened in 10 steps. 1:Drive Time basis for step interval of slat (10), 100 ms 1:Drive Factor for step interval of slat 5-255 Pause on reverse for change of direction When the blind actuator moves and receives a command to move to the opposite direction, it stops and waits for the pause of reverse interval to pass. Caution! Pauses on reverse interval that are too short could cause damage to the drive. When setting the values, observe the manufacturers specification for the drive under all circumstances. 1:Drive Pause on reverse on change in direction (1-255) factor * 100 ms ms 16
Additional weather alarm and automatic function Caution! When the blinds or other hangings are mounted on the outside of the window the use of automatic weather alarm functions are recommended. A weather station is not a part of this room-solution and has to be ordered separately. We recommend using at least one weather station for each facade with outside mounted blinds. For the detailed planning (e.g. thresholds) you have to observe the manufacturers specifications for the drive under all circumstances. This shutter and blind solution is prepared for A-class. A-classification needs additional functionality, which realises an automatic pulling down of the shutter or blind dependant on the outside temperature and lux value, in order to save the room from outside thermal influences. This automatism will be controlled by a central control unit (central building management function) plus a weather station sensing conditions outside the building. fine tuning A description on an exemplary functionality is shown in Appendix 1 SB, which will be automatically added to your project s document-folder, when selecting a solution with shutter/blind functionality to your project. Power failure behaviour Switch actuator: Relay state after bus voltage failure: no change (relay remains) Control unit 0-10V: Relay state after bus voltage recovery: opened (light is OFF) Blind actuator: Behavior when bus voltage fails: no reaction (relay remains) Blind actuator: Behavior on bus voltage recovery: stop (no movement) When you want to set another behavior for the blind actuator you can enable the parameter page failure mode.

User manual The user manual provided for the application is an end users training material and can be installed at site when final submission is made. Please do no forget to cut out this quick guide for the user and attach to the wall next to the entrance to the room. Also, make sure the customer is aware of the installed applications function. Quick guide This room is equipped with movement dependent automatic light control with light regulation and manual control, shutter/blind and temperature control. Lighting control Automatic mode operation The lights are automatically switched ON when a person enters the room and the brightness value is below the selected brightness threshold. If no movement is detected within a delay time of 25 minutes, the light will be dimmed down to minimum. If no movement is detected for another 5 minutes the light will be switched off. When the lights are on, the light controller in the presence detector maintains the decided lux set point by sending dimming telegrams to the lamp actuator. If the daylight will increase, the regulation dims down the artificial light. If it decreases, the regulation will dim up the artificial light. 1 2 3 4 5 6 7 8 Manual mode operation The user can also select the lux set point by the pushbutton unit. Button 1 will give high brightness (500 lux), button 2 will give medium brightness (300 lux) and button 3 low brightness (100 lux). With button 4 permanent-off can be activated. The light will then be off until one of the other buttons is pressed. When permanent OFF is activated the status LED next to the button is blinking. 06-10 Application 8.2.1.0.0.4 service for your customer 18
User manual Quick guide This room is equipped with movement dependent automatic light control with light regulation and manual control, temperature control. Temperature control, heating/cooling Movement detection will automatically set the temperature control into comfortmode. To save energy this will not happen until a person has been in the room for more than 3 minutes. In this way the temperature control is not affected if someone is present in the room just for a short period of time. If no movement is detected within a delay time of 25 minutes the temperature control is set into standby-mode. invisible buttons 1 2 3 4 5 6 7 8 Comfort-mode: default room temperature set point, heating 21 C cooling 24 C Standby-mode: default room temperature set point, heating 19 C cooling 26 C Frost/Heat protection: heating 7 C cooling 35 C The set point can be adjusted by the user +/- 3 C from given set point. This is done by pushing invisible buttons on both sides of the display frame. If a window contact (breaking contact) is connected to the EMO valve drive, the temperature control will be set into frost/heat protection mode when the window is open. 06-10 Application 8.2.1.0.0.4 service for your customer 19
User manual Quick guide This room is equipped with movement dependent automatic light control with light regulation and manual control, temperature control. Blind/shutter control A blind or roller shutter motor with end position can be connected to each channel of the blind actuator. The position of the blind s or shutter s height can be adjusted manually by push-buttons. With a long push on button 5 the blind or roller shutter moves upwards. With a long push on button 6 the blind or roller shutter moves downwards. With a short push the movement of the blind or shutter stops. In the case of a blind or hanging with slats the angle of the slats can also be moved stepwise with several short pushes. With button 6 the slats turn to the position 100% closed or to the mechanically determined working position. With button 5 the slats move to the opposite direction. The possible angles of the slats depend from the mechanical construction of the blind with slats. 1 2 3 4 5 6 7 8 Scene control A scene for a beamer presentation can be recalled with button 7. Thereby the blinds or shutters will be lowered to 80% closed and the light will be set to a low lux-level (50 lux). By use of button 8 the blinds or shutters will be moved completely upwards again and the standard lighting level (500 lux) will be activated. 06-10 Application 8.2.1.0.0.4 service for your customer ISC02082_EN 20
